Network traffic
Traffic types
Two main types of communication occurs in the CARESCAPE Network:
Broadcast and Unicast.
 Broadcast traffic is sent from one device to all devices on the
network. Examples of CARESCAPE broadcast traffic are device
discovery, alarms, and time synchronization.
 Unicast traffic is sent from one device to another specific device on
the network. An example of CARESCAPE unicast traffic is patient
waveforms.
Flow
 Upstream broadcast: The Dash patient monitor sends broadcasts to
other network devices.
 Downstream broadcast: The Dash patient monitor receives
broadcasts from other network devices.
Most of the Dash network problems are broadcast related. If broadcast is
not working, it is unlikely that unicast communication can work.
